Leigh syndrome associated with a mutation in the NDUFS7 (PSST) nuclear encoded subunit of complex I.
Leigh syndrome is the phenotypical expression of a genetically heterogeneous cluster of disorders, with pyruvate dehydrogenase complex deficiency and respiratory chain disorders as the main biochemical causes. We report the first missense mutation within the nuclear encoded complex I subunit, NDUFS7, in 2 siblings with neuropathologically proven complex I-deficient Leigh syndrome.
متن کاملRapid identification of a novel complex I MT-ND2 m.10134C>A mutation in a Leigh syndrome patient
Leigh syndrome (LS) is a rare progressive multi-system neurodegenerative disorder, the genetics of which is frequently difficult to resolve. Rapid determination of the genetic etiology of LS in a 5-year-old girl facilitated inclusion in Edison Pharmaceutical’s phase 2B clinical trial of EPI-743. SNP-arrays and high-coverage whole exome sequencing were performed on the proband, both parents and ...

متن کاملThe p.M292T NDUFS2 mutation causes complex I-deficient Leigh syndrome in multiple families
Isolated complex I deficiency is the most frequently observed oxidative phosphorylation defect in children with mitochondrial disease, leading to a diverse range of clinical presentations, including Leigh syndrome. For most patients the genetic cause of the biochemical defect remains unknown due to incomplete understanding of the complex I assembly process. Nonetheless, a plethora of pathogenic...
متن کاملLeigh syndrome associated with mitochondrial complex I deficiency due to a novel mutation in the NDUFS1 gene.
BACKGROUND Mutations in the nuclear-encoded subunits of complex I of the mitochondrial respiratory chain are a recognized cause of Leigh syndrome (LS). Recently, 6 mutations in the NDUFS1 gene were identified in 3 families. OBJECTIVE To describe a Spanish family with LS, complex I deficiency in muscle, and a novel mutation in the NDUFS1 gene. DESIGN Using molecular genetic approaches, we id...
